"Hong Kong is geographically compact and boasts one of the world's most efficient, safe, affordable and frequent public transport systems." The site where that statement originally was to be found is the province of the Hong Kong Tourism Board but I actually would agree 100% with it. What's more, despite what the second photo in this entry may get you thinking, public transport is the choice of the majority of the territory's population; with over 90% of daily journeys being made on various modes of public transport that, as I trust the photos do show, are pretty clean and colorful as well as efficient, safe, etc, etc.
The stations of the Mass Transit Railway (MTR)'s largely underground trains tend to have single designated colors (though the Choi Hung MTR station as well as the nearby Choi Hung Estate lives up to its name (choi hung means "rainbow" in Cantonese)). In the case of the Tin Hau MTR station that derives its name from a nearby temple to the goddess of the sea, that color is -- you guessed it! -- orange. And when that designated color is the color of that station's walls but also its ceilings, pipes and other accoutrements, I think you'd agree that it consequently makes for a good subject for this week's Photo Hunt! :)
